在所有窗口上方运行hta [英] Running an hta above all windows

问题描述

我有一个HTML应用程序，希望保留在所有窗口的顶部(也就是说，如果另一个窗口被打开/切换到该窗口，我希望该窗口覆盖它). JavaScript解决方案在Windows 7/IE9模式下不起作用(不确定是哪种阻碍，也不能更改)，并且VBScript解决方案似乎完全失败或依赖于外部组件.我也不能使用模式对话框，因为我需要将其置于所有其他窗口之上，而不仅仅是其父窗口.

I have an HTML application that I want to stay on top of all windows (that is, if another window is opened/switched to, I want this one to cover it). JavaScript solutions don't work in Windows 7/IE9 Mode (not sure which is holding it back, can't change either), and VBScript solutions seem to either fail outright or depend on outside components. I can't use modal dialogs either because I need this to be on top of ALL other windows, not just its parent.

请勿将此标记为

And don't mark this as a duplicate of https://stackoverflow.com/questions/24539339/how-to-open-a-hta-window-on-top-of-all-other-windows because that (unfortunately still unanswered) question refers to opening above other windows, not maintaining stack position.

我尝试过的事情:

• 概述的三个建议此处.
• JavaScript解决方案此处.
• 小的VBScript 此处.
• 上述各项可能有十几种或更多的细微变化.

• Three of the suggestions outlined here.
• The JavaScript solution here.
• The little VBScript here.
• Probably a dozen or more subtle variations on each of the above.

请记住，我无法下载额外的组件(没有autoit或nircmd).都应将其集成到单个文件中，最好是hta，而不是zip.

Keep in mind that I can't download an extra component (no autoit or nircmd). It should all be integrated into a single file, preferably an hta, but not a zip.

仅略微修改了Teemu的解决方案，主要是为了便于携带(以防万一).

Only very slightly adapted from Teemu's solution, mainly for portability (just in case).

<script language="javascript">
    var locationstore = location.href
    [...]
    window.onload = function () {
        var shell = new ActiveXObject('WScript.Shell'),
            forceModal = function (e) {
                shell.Run(locationstore, 1, 0);
            };
        top.addEventListener('blur', forceModal, false);
        window.onbeforeunload = function () {
            window.removeEventListener('blur', forceModal, false);
        };
    };
</script>

推荐答案

这是一个邪恶的代码段.它不是完美的，但是也许您可以进一步开发它.

Here's an evil snippet. It's not perfect, but maybe you can develope it further.

window.onload = function () {
    var shell = new ActiveXObject('WScript.Shell'),
        forceModal = function (e) {
            shell.Run('absolute_path_to_hta', 1, 0);
        };
    top.addEventListener('blur', forceModal, false);
    window.onbeforeunload = function () {
        window.removeEventListener('blur', forceModal, false);
    };
};

警告:测试此代码段时，HTA必须在单实例模式下运行.

WARNING: HTA must run in single instance mode, when testing this snippet.
